Sorry, I didn't look closely enough yesterday. This also happens with my
previous test as well. So it is obviously not a bug with
gdb_continue_to_end.

I am still debugging this, I never saw this before a recent rebase.
It seems like gdbserver is exiting too early, I am not even hitting
the BPs for the second matrix branch.
